title: Effect of aldehydes on polyamine metabolism. I. Method used to determine CO2 produced "in vitro" in enzymatic reactions: its application in evaluation of S-adenosylmethionine decarboxylase (SAMD) activity.
abstract: In this paper the Authors describe a new method they have adopted (in studies reported in accompanying papers II and III) for measuring S-adenosylmethionine decarboxylase activity in entire cells and cell fractions. The new method is a general one for recovering and measuring labelled carbon dioxide formed "in vitro" during enzymatic reactions. It presents several advantages when compared to traditional methods.
